Clinical Trial Summary

The primary objective of this study is to evaluate the impact of substance-abuse treatment as usual plus smoking-cessation treatment (TAU+SCT), relative to substance-abuse treatment as usual (TAU), on drug-abuse outcomes. Specifically, this study will evaluate whether concurrent smoking-cessation treatment improves, worsens, or has no effect on stimulant-use outcomes in smokers who are in outpatient substance-abuse treatment for cocaine or methamphetamine dependence.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Stimulant-free Weeks Assessed by Self-report and Twice-weekly Urine Drug Screens	Stimulant-free week results (no cocaine, methamphetamine and amphetamine use) were obtained by combining the urine drug screens (UDS) and the self-reported Timeline Follow-Back (TLFB). At the group level, this outcome translates into the percentage of weeks in each study arm that are stimulant-free.	Week 16
Secondary	Point-prevalence Abstinence (Smoking Outcome)	point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level = 8 ppm	Week 10 assessment
Secondary	Four Week Continuous Smoking Abstinence	A combination of daily self-reported smoking data and weekly carbon monoxide levels were used to determine continuous abstinence during post-quit days 15 - 42.	Post-quit days 15-42
Secondary	Stimulant-free Results at 3-month Visit	At the 3-month follow-up visit, percentage of participants with a negative urine drug screen for stimulant use and no stimulant use days reported during the past 28 days based on Timeline Follow-back.	3-month follow-up visit
Secondary	Point-prevalence Abstinence (Smoking Outcome) 3 Month Visit	point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level = 8 ppm	3- month follow-up visits
Secondary	Stimulant-free Results at 6-month Visit	At the 6-month follow-up visit, percentage of participants with a negative urine drug screen for stimulant use and no stimulant use days reported during the past 28 days based on Timeline Follow-back.	6 - months follow-up visit
Secondary	Point-prevalence Abstinence (Smoking Outcome) 6 Month Visit	point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level = 8 ppm	6 month visit
